So I have a 1j in my s13 and it keeps cutting fuel. It didnt do it until I hooked up my AFC NEO but I unhooked it and it still does it. I also pot in a Turbo XS fuel cut defender and it didnt help. Do I need to find the Greddy Boost Cut Controller? Or is it something else? Car runs and pulls great until you mash the gas. Anything below 50% throttle is amazing.

Mod list
Turbo XS Fuel Cut Defender
3" Y pipe/Down Pipe
3" Intake with cone filter
Aeromotive FPR
Walbro fuel pump
Driftmotion pullys
ORC Single Plate
3" Intercooler piping with big front mount Intercooler
2jz MAP

Thanks

Sounds to me like your coils are cracked. Mine did the same exact thing. Put nail polish on the cracks and used a heavy duty heat shrink and took care of my problem....... well until my ecu crapped out
